Name of the Condition

• Common Name: Congenital Shortening of Right Lower Limb
• Medical Term: Congenital Anomaly of the Lower Limb
• ICD Code: Q72.811

Summary

Congenital shortening of the right lower limb is a birth defect where a baby is born with one leg shorter than the other. This can affect mobility and may require medical intervention to improve function and alignment.

Causes

The exact cause of congenital shortening of the lower limb is often unknown. It is believed to result from a disruption in fetal development, which may be influenced by genetic factors or environmental exposures during pregnancy.

Risk Factors

• Family history of limb defects
• Genetic disorders
• Maternal exposure to certain medications or toxins during pregnancy
• Insufficient blood supply to the fetus during limb formation

Symptoms

• Noticeably shorter right leg at birth
• Difficulty with movement or achieving motor milestones
• Possible muscle weakness or gait abnormalities

Diagnosis

• Physical examination
• Imaging studies such as X-rays, MRI, or ultrasound to assess limb length and structure

Treatment Options

• Physical therapy to improve strength and mobility
• Orthotics to support limb function
• Surgical interventions, including limb lengthening procedures, to achieve better symmetry

Prognosis and Follow-Up

Prognosis varies with the severity of the condition but generally, with appropriate treatment, individuals can achieve improved limb function. Regular follow-ups are necessary to monitor growth and development and adjust treatments as needed.

Complications

• Differences in limb length can lead to issues with posture and walking, potentially causing scoliosis or joint problems over time.
• Psychological impact due to differences in physical appearance or mobility challenges.

Lifestyle & Prevention

• There are no specific preventive measures due to the congenital nature of the condition.
• Maintaining general prenatal health and avoiding harmful exposures during pregnancy may reduce risks.

When to Seek Professional Help

• If a noticeable difference in limb length is observed in a newborn
• Development of gait abnormalities as the child grows

Tips for Medical Coders

• Ensure accurate coding by confirming laterality and congenital nature (Q72.811 specifically denotes the right lower limb).
• Avoid misclassification with acquired limb discrepancies or other congenital limb anomalies not specified for the lower limb.
